Carbonating vessel



Nov. 1, 1932. H. R. BOYER CARBONATING VESSEL Filed Feb. 15, 1932 ATTORNEYaS' Patented Nov. 1, 1932 PATENT OFFICE HAROLD It. BOYTJR, OF GROSSEPOINTE FARMS, MICHIGAN CARBON .ATIN G VESSEL Application filed February15, 1932. Serial No. 593,164.

The invention relates to apparatus for carbonating liquids and it is theobject of the invention to obtain a simple and inexpensive constructionof portable apparatus which can be used for this purpose.v To this endthe invention consists in the construction as hereinafter set forth.

In the drawing:

Figure 1 is a vertical central section through the carbonating vessel;

Figure 2 is a horizontal section on line 2-2 of Figure 1;

Figure 3 is a top plan view.

The tank or vessel is formed of a pair of pressed sheet metal cups A andB having their peripheral edges welded together at C. The lower cup Bhas an indrawn central portion B and the upper cup A is fashioned toform an upwardly extending neck portion D with a radially inwardlyextending flange E surrounding the central opening. The neck portion Dis slightly return bent so as to form an outwardly extending bulge orbead D with a contracted portion 1) between the same and the top wall ofthe cup.

F is a split band for surrounding the neck D and which is of aconcavo-convex section so as to fit over the bead D. On opposite sidesof the split the band F is provided with lugs F which are securedtogether by a clamping screw G, thereby holding the band firmly clampedto the neck. H is a cover plate having a downwardly extending flan e Hfor fitting within the annular flange and for receiving thereabout asealing gasket I. The cover plate H has a plurality of lugs H atdistributed points around its periphery apertured for the passage of aclamping screw which clears the bead D and engages threaded apertures inlugs F on the band F. Thumb screws J engage these lugs to clamp thecover upon the tank and to form a hermetic seal.

The cover plate H has formed integral therewith a discharge fitting K towhich is connected a tap Leontrolled by a valve M. A pressure gauge N ismounted on the cap H to communicate with the space within the tank and apop safety plug 0 .in, the gas injection valve stem P is also mounted onthis cap. A tube Q connected to the fitting K depends obliquelytherefrom and is of suflicient length to extend down into the annularportion of the bottom of the tank surrounding the indrawn portion B.

With the construction as described, the liquid to be carbonated is firstfilled into the tank after which the cover is placed in position andclamped down to form a hermetic seal. The carbonating gas may then beinjected through the valve stem P, the pressure being indicated upon thegauge N. The tank may then be rolled or agitated in any way tofacilitate the absorption of the gas by the liquid. Then the process iscompleted the carbonated liquid may be drawn oil by opening the tapvalve M, the gas pressure serving to discharge-the liquid through thepipe Q.

The manufacturing cost of this a paratus is comparatively low, as thecups X and B may be formed of pressed sheet steel and after weldingthese sections to each other, the whole tank may be enameled bothoutside and inside. The other elements of the structure are cheaplymanufactured and easily applied.

What I claim as my invention is:

1. An apparatus for carbonating liquids comprising a tank formed of twopressed metal cups having their edges welded together, the upper cupbeing provided with a neck portion having an annular bead pressedtherein and also provided with a radially inwardly extending flange atits upper end, a grooved split band or collar clamped about said bead, acap, clamping bolts for securing said cap upon said flange, said boltsengag ing threaded apertures in said band or collar, a discharge fittingintegral with said cap and projecting laterally therefrom, a tubeconnected to said fitting and projecting downward to the bottom of saidtank, a valve stem connected with said cap for the introduction of gasinto the tank and a valve controlled tap connecting to said fitting.

2. An apparatus for carbonating liquids comprising a tank formed of apair of pressed sheet metal cups having their edges Welded together, thebottom cup being centrally pressed inward to form an annular trougharound its outer edge, the other cup being provided with'a neck portionwith an annular cad pressed therein and a radially inwardly extendingflange at its upper end, a split'band or collar grooved to fit aboutsaid bead and clamped upon said neck, said band being provided with ahandle portion projecting therefrom, a cap provided with a dischargefitting and a tube extending downward from said fitting and inclined toengage its lower end in the annular trough surrounding the inwardlypressed central portion of the tank, bolts for securing said cap uponsaid flange, said bolts engaging threaded apertures in said split bandor collar, a valve stem connected to said cap for introducing gas intothe tank, a valve controlled tap connecting tosaid discharge fitting anda safety pop valve also connected to said cap.

3. An apparatus for carbonating liquids comprising a tank provided witha neck portion with a surrounding bead thereon, a cap for closing thetank and a split band or collar grooved to fit about said bead andclamped u on said neck, said band being provided with'a handle portionprojecting therefrom and lu s distributed thereabout having threadeapertures therein and clampin screws for said cap engaging said threadeapertures.

In testimony whereof I aifix my signature.

HAROLD R. lEOYER.
